Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electroplating, and particularly relates to a swinging tank device for a nickel electroplating process. BACKGROUND

[0002] In the field of electroplating process, nickel plating is widely used in workpiece surface treatment due to its excellent corrosion resistance and wear resistance. However, during the process of nickel plating, hydrogen bubbles are easily retained on the surface of the workpiece. These bubbles can form pinholes, pitting and other defects in the plating layer, seriously damaging the compactness of the plating layer and the appearance quality, reducing the performance and service life of the workpiece, and becoming a key bottleneck restricting the quality improvement of the nickel plating process.

[0003] To improve the flow state of the plating solution and reduce bubble retention, traditional electroplating tanks mostly use mechanical stirring or air stirring. However, there are significant defects in practical application: first, the plating solution does not penetrate uniformly. For workpieces with complex structures such as deep holes and grooves, traditional stirring cannot make the plating solution fully reach all surfaces of the workpiece, resulting in insufficient plating in some areas; second, the bubble retention problem has not been effectively solved. Hydrogen bubbles are still easily attached to the surface of the workpiece and cannot be completely removed by simple stirring, which further causes defects in the plating layer; third, the plating layer thickness is uneven. Under static or simple stirring mode, the distribution of metal ions in the plating solution is uneven, resulting in a large difference in deposition rate of metal ions on the surface of the workpiece, making it difficult to form a plating layer with uniform thickness; fourth, the loading capacity is limited. The fixed structure design of the traditional tank body is not reasonable, resulting in a limited number of workpieces loaded in a unit space, which restricts the improvement of production efficiency; therefore, a new type of electroplating swinging tank device is needed to solve the above problems.
